I m 21 years old and I recently had intercourse with my boyfriend in the I guess all fours position on a big chair and we were in that position for a while longer than usual. Immediately after my thighs had gone numb. Just my thighs, my right leg went back to normal but a part on my left leg is still numb ish. I can feel it when I press on it and stuff but it still has that numb feeling not intense but enough to know it doesn t feel quite right. Is this normal ? Should I be concerned ? This is the first time this has happened to me so I m a little worried.
